2.1 What is System?
2.1.1 Definition of System
A system is something which gives an output when it is provided with an input (see figure 1).

 2.1.2 System-on-Chip(SoC)
As the name suggests, its basically means shrinking the whole system onto a single chip.The most important feature of the chip is that its functionality should be comparable to that of the original system. It improves quality, productivity and performance.
